IHI VF43 Turbocharger

The VF43 comes stock on the '07 WRX STi, and is a terrific upgrade turbo for the 2.0 WRX. It's just like the older VF39, but this turbo sports an upgraded wastegate design for better boost management. It can support up to 320 hp at the wheels, and it bolts right up. It'll fit great on the Forester XT, too. Model car not included. :)
